# Two coherent sources  and  are separated by a distance four times the wavelength  of the source. The sources lies along  axis whereas a detector moves along  axis. Leaving the origin and far off points the number of points where maxima are observed is

## Question ID - 150099 :- Two coherent sources  and  are separated by a distance four times the wavelength  of the source. The sources lies along  axis whereas a detector moves along  axis. Leaving the origin and far off points the number of points where maxima are observed is

3537

From ,

Here  is the path difference  for maximum intensity

Or

Then

Number of points for maxima becomes 3
